At one end of thecasing is a common nipple having openings 6 and I therein which connectto the inlet 2 and 7 outlet 3 respectively. These openings may be'round, as shown, or of any shape Iandmay extend thru the valve casingany manner.

The openings 6 and I are connected" by vertical passages 8 and 9 to thevalves and the valves are located in the lower ends of openings Ill andl I. As thevalve members andope'rating parts are identical, the samereference numerals will be used for both in the following description.In the lower-ends of the valve openings are valve seats l2 which'may bemadeof bakelite or any suitable material and the valve closing membersl3, which-are threaded in the lower portion of the valve openings, areprovided with surfaces which engage the surfaces of the valve seats l2.These members I3 are providedwith recesses I5 in their lower ends andslots IS in their upper ends into which tongues I! on the lower end ofthe valve operating members l8 extend and it will be noted that as thevalve operating members are rotated, they will rotate the valveolosingmembers l3" and move them upward or downward thru"the threads.

The valve operating members 18 are slidably.

held in glands l9 which are threaded in the'upper ends of the openingsI0 and II and the upper ends of these members are provided with squareshanks 20 by which they may be" turned by a wrench or the like. Althoughthe shanks 20 areshown as being square, it will be understood that theymay behexagonal, or provided with any number of sides or formed'inar'iymanner so that they may be'gripped androtated in .order 'to adjust thepositions'of the valves. Theglands are provided'with nuts 2| so thatthey may also be gripped and turnedand it will be understood that anypacking means may be used or any means maybe used'fcr packing the upperends of thevalve members. V v

The connections 2 and 3 are provided with openings 22 and 23 whichextend thru the casing and communicate with the lower ends of theopenings I0 and II around the valve members so that as themembers 13 areraised, fluids may pass from the openings'G and 1 thru the passages 8and 9 thru the" valves, and also-thru the passages-22 and '23. i V

Inthe design shown the connection 1' is provided with an extension 24which extends thru a nipple 25 at one side of the casing and a relief orblow-off gasket '4 is threaded on this nipple and forms a-closure fortheextension 2 Between the inner surface of the' gasket and the end ofthe nipple is a thin copper disc 26 which completely closes thisconnection, however,

should the pressurein the passage or in the container to which thepassage is connected exceed a predetermined amount, it-vsrill blow outthe disc 26 and'thereby relieve the pressure. The member disprovidedwithja recess 21 and openings 28-which connect the interior thereof tothe atmosphere. It will be understood that any other material may beused instead of copper for the disc 26 and any other means may be usedfor providing a blow-01f connection. It will also be understood that theblow-off connection may be provided in the opening 6 instead of theopening 7 or similar connections may be provided in both openings, asmay be desired.

It will be understood that other-changes may be made in the devicewithout departing from the spirit of the invention. One of which changesmay be in the use of a housing of any other design or arrangements,another may be in the location of the inlet and outlet connections, asit will be .noted that both of these may be made from the same side orfrom any other point or points of the housing, another may be in the useof valves of a different type, another may be in the use of other meansfor operating the valves, another may be in' the locationof the valveoperating means, and still another may be in the use of other means forproviding a blow off connection or'means for relieving the pressure whenthe pressure exceeds a predetermined amount.

The construction will readily be understood from theforegoingdescription. In use the valve may be provided as shown anddescribed audit will be noted that it may be screwed into the opening ofa C02 container with the inlet and outlet connections connected to afilling or supply container with the inlet connection connected to thelower end of the container and the outlet connectionconnected to theupper end thereof. It will,therefore, be noted that as the inletconnection is' opened, carbondioxide will be transferred from theupperor filling container to the other container by gravity and carbondioxidegas will pass from the lower container backward to the top of the upperor filling container thru the return connection. This device may readilybe installed as it is only necessary to remove the closure'from the CO2container and insert this valve, and then make the connections from theinlet and outlet openings to the lower and upper ends of the supply orfilling container respectively. The valves in the passages thru thehousing may readily be set to permit any desired amount of fluid to passthru the device and these may be regulated as may be desired. With theconnections formed in this manner carbondioxide may readily betransferred from one container to another and as the return passage isprovided with a blow-off or pop-off connection, all danger is removedand'one container'after another may readily be filled.

Having thus fully described the invention what I claim as new and desireto secure by Letters 'Patent, is:

- i 1. A valve of the type having a substantially flat body portion withparallel openings therein andhaving anipple extending from one endthereof with independent parallel passages extending thru said nippleand communicating with said parallel openings, said body portion havinglaterally, extending openings also communicating with said parallelopenings and extending thru threaded nipples extending outward from thesides thereof, valve seats in the inner ends of said parallel openings,valve members in said parallel openings adapted to engage said valveseats, valve stems extending from said valve members thru the outside of'said valve body freely connected to said valve members, and bushingsthreaded in said valve body around said valve stems.
